Abstract
A dental impression paper tray comprising a material mainly composed of pulp which is compressed molded to a dental impression tray shape having a thickness of 0.5-10 mm. Minute concavities/convexities may be formed at least on the inner surface of the paper dental impression tray. Paraffin wax may be dispersingly included in the tray or coated on the surface of the tray. A handle of the tray may be integrally attached to a dish portion by insertion or adhesion. Since the tray is made of paper and is less expensive, it can be domestically disposed with an incinerator as a disposal tray. Further, the tray having the minute concavities/convexities has an increased holding force to an impression material. The tray to or in which paraffin wax is coated or contained has increased water resistance.
